At 1:15 in Mrs. Northards computer science classroom in middle school she speaks to students obnoxiously loud like a hyena. This noise disrupts innocent working students in the hallway.

This is yet another example of how teachers should maintain control of their classrooms and or close all areas for noise to escape when they know they will be heard by another class.

The same goes for hallways in passing time when students are diligently working in classrooms whether it be on homework or standardized tests are all of sudden overwhelmed by the rush of noise emerging from the hallway.
